Question

the zeros of the quadratic polynomialx²-x-12 is
a)both negative
b)both positive
c)one positive one negative​

Answer 1

Answer:

c) one positive and one negative

Step-by-step explanation:

f(x) = x²-x-12 -> -12 -> -4+3

=( x-4)(x+3)

x = -4,3

Answer 2

Answer:

Given polynomial is x²-x-12

Sum of zeroes = x

Product of zeroes = -12

∵ product of zeroes is negative and sum of zeroes is positive, this is only possible if both should be negative.

∴ one positive and one negative
